I have had Tivo for about 5 years now, but am having a problem I've never had before. I've tried everything I can think of to fix it, and it's really driving me insane! My comcast cable box and my Tivo don't seem to be getting along all of a sudden. I haven't connected anything differently than ever before. But, I'll notice every now and then that the channel display on the cable box will be scrolling... it'll be on channel 13 and then I'll look up and all of a sudden, it's on 395 or something like that. Then, I'll be watching something on Tivo, and all of a sudden, it's a solid blue screen and nothing is taped. OR, it will display one show and another complete channel will be what it actually taped. The sound will be distorted, or the picture will just be frozen in the middle of an otherwise normal taping. I don't know why I'm having all these issues all of a sudden, after so long! Is it my cable? Is it my Tivo? Is it both? I have no idea, and honestly, I'm just not a techie person and I have no idea where to even start to try and fix this.
